Application filed January 27, I919. Serial No. 273,355.

good condition. I am, of course, awaretha't devices have heretofore been provided for this purpose,,but my invention has certain improvements in view. V 1

In carrying out the invent1on,"I employ an oil tank open-at its upper end, a plurality of oil pans on the exterior of the tank and communicating with the latter, oil applying members rotatably mounted 'on the exterior of the tank and dipping into said pans, an oil reservoir received removably in the tank, and a valve for controlling the discharge of oil from said reservoir intosaid tank.

'One object of the invention isto provide reinforcing bars secured to the inner side of the tank wall to stiffen such sides and prevent bending thereof as the hogs rub against the oil applying members; and a further object is to provide the aforesaid bars with shoulders upon whichth'e oil reservoir is supported. V 7

An additional object is to provide a novel mounting for the rotary oil applymg {members which will permit them tov be Vertically adjusted. for dipping a greater or lesser Astill further ob]ectis to provide anovel form of valve for supplying olltothe tank by means of a screw threaded; filling plug with which said reservoir is provided I 4 With the foregoing in view, the invention resides in a number ofnovel'featuresof construction and unique arrangements of. parts vto be hereinafter fully describedand claimed,-the descriptive matter being supplemented by the accompanylng drawings whichillustrate one form of the invention.

Fig. 5 is :a side elevation oftlie valve guide I stem, showing the valveremoved and in vertical section. V v V Fig. 6 is a horizontal section on the plane of the line 6'6 of Fig. 5.

Inthe drawings above briefly described, thenumeral 1 designates an oil tank open at its top and supported on suitable feet or the like 2,-v sjaid tank being shown in the present form "of the invention as having its wall formed of four sides 3 whose upper ends are shown rounded, although this is not essential. Mounted on the exterior of the tank 1 andv carried one by each side 3 thereof, are suitably shaped oil pans 4 whose bottoms are preferably in a plane below the bottom of the -,tank. By means of oil reservoir 5 received removably in the tank 1, oil is sup- .plied to said tank andsuch oil is fed from the tankto the pans i through vertical slots 6 formed in the tank sides 3. These slots also perform the additional function f .allowing vertical adjustment of hemispherical oil applying members 7, said members being rotatably mounted on. the exterior of the tank 1 and dipping into the pans 4, so "that as the, hogs rub against said members, 7 and the latter are thus rotated, oil will be appliedto the hogs? .hides.

-,"-F o.r mounting the oil applying members 7, circular bearing members Scontact against the outer faces ofthe tank sides 3 and said oil applying members are provided with hubs 9 rotatable upon thebearing members. Bolts 10.;pass inwardly through the anembers'? and have their heads .11 countersunk in thelouter ends of "the latter, said bolts extending-through the unembers 8 and slots 6 as seen clearly in Figs. 2 and 3. Nuts or other.s11itable shoulders 12 are provided on the bolts and contact against the outer sides of the bear ng members :8 so that tightening of thenuts 13 on the sinner ends of said-bolts Qwill clam-p vsaid bearing members tightly :against the outer faces of the tank sides 3. flihe' nuts 18 bear against the inner faces of ,".the aforesaid tank sides and when these nuts are loosened, the bolts 10, hearing members 1 oil applyingmembers 7, may be adjjnsted vertically ito .allowfthelatter to dip a greateror less distance into the; oil in the pans 4:. The outer ends of the members 7 are Preferably provided with rounded projections or the like 14 to provide efliclent rubbing surfaces.

The oil reservoir 5 is provided with a top 15 having eaves 16 which project from the sides of the reservoir to such an extent as to exclude rain and the like from the pans 4, as far as possible, but in order to allow any water which may enter said pans to drain out, without causing the pans to overfiow and waste the oil, I provide water outlet passages 17 which are illustrated in elevation in Fig. 1 and in section, in Fig. 2. These passages are shown in the form of tubes on the exterior of the pans 4, leading from the bottoms of said pans to a point at substantially the level of the oil in the pans 4:. Any water will collect at the bottoms of the pans 4 and will drain therefrom through the tubes 17, instead of causing these pans to overflow and waste the oil. Each pan, in addition to the tube 17 is preferably provided with a drain cock 18.

The reservoir 5 could be supported in the tank 1 in any preferred manner, but in order to reinforce the sides 3 of said tank against bending as the hogs rub against the members 7, I provide the inner faces of said sides with vertical reinforcing bars 19, and

I prefer to provide the lower ends of these I bars with shoulders 20 for supporting the reservoir at the proper distance from the tank bottom to allow for operation of the valve yet to be described. I have shown a rectangular plate 21 resting on the shoulders 20 and the bottom of the reservoir resting upon said plate, but in some instances, the plate 21 might be eliminated and the tank bottom would then rest directly upon the shoulders 20. The plate 21 is notched at to receive the bars 19 and at its center, said plate is provided with an opening 23 through which 'a-sleeve 2a depends from the bottom of the reservoir 5.

Sleeve 24.- forms a valve seat and although this sleeve'could be secured in place in any preferred manner, I preferably provide the same with an annular flange 25 secured upon the upper surface of the bottom of the reservoir. A hollow cylindrical valve stem guide 26 rests at its lower end upon but is unsecured to the flange 25, the upper end of said guide having a head 27 while the lower end thereof is equipped with inwardly extending guide ribs 28. A vertical valve stem 31 passes slidably through the head 27 and carries a yoke 29 which slides on guide pins 30 rising from the member 26. The stem 31 rises to a point adjacent the top of the reservoir and extends downwardly through the member 26. into the sleeve 24. A suitable valve 32 is removably threaded on the lower end of the stem 31 and coacts with the lower end of the sleeve 24:

in controlling the discharge of oil from the reservoir 5 into the tank 1, the sides of the guide member 26 being provided with slots 33, through which the oil may pass. A coiled spring 34 surrounds the stem 31 and bears at its lower end against the head 27, while the upper end of said spring thrusts against the yoke 29 so that it will exert an upward stress upon the latter, tending to close the valve 32. The downward thrust of the spring 3% retains the entire valve guiding means in place but when the valve 32 is removed as seen in Fig. 5, the stem and its guiding means may be withdrawn upwardly through a filling neck 35 with which the reservoir top 15 is provided. A filling plug 36 is threaded in the neck 35 and is preferably formed with a recess v37 in its lower end. The recess 37 receives the upper end of the valve stem 31 and by threading the plug downwardly into the neck 35 beyond a predetermined extent, the valve will be opened as seen in Fig. 4, thus permitting a quantity of oil to be discharged from the reservoir 5 into the tank 1, and from this tank into the oil pans 4:, by way of the slots 6. l/Vhen the plug 35 is threaded upwardly as disclosed in Fig. 2, the spring 34 will retain the valve 32 in closed position to prevent the discharge of oil.

The valve 32 may be kept normally closed and only opened when it is necessary to supply the tank and oil pans with more oil,

or the valve may remain open to maintain a.

constant level'of oil in the tank. hen this manner of operation is adopted receding of the oil level in the tank from the lower end of sleeve 24, will permit air to enterthe reservoir 5 and will consequently allow a quantity of oil to discharge therefrom. The moment the oil level in the tank rises snfficiently to close the sleeve 24 against the entrance of air, the discharge of oil will be checked, since it cannot leave the reservoir until air is allowed to enter the latter.

It will be observed by reference to Figs.

' 2 and 5, that when the valve 32 is removed from its stem 31, the entire valve guiding means and said stem may be withdrawn through the neck 35 of the reservoir, for repairing, cleaning, etc. The detachment of the valve also permits easy grinding of said valve and its seat 24. It is also ratherimportant to observe'that when the plug 36 is removed for filling the reservoir 5, the valve 32 is closedby the spring 3 1-. 'By this arrangement, if the liquid seal manner of opi eration is used, the contents of the reservoir will not be discharged as would otherwise occur, due to the entranceof air through the open neck 35. 1 2- Other rather important features of the invention are the novel mounting of the oil applying members 7 for permitting vertical adjustment thereof, and the provision of the for the reservoir 5. The sides of this reservoir are shown provided with recesses 38 which receive the bars 19 and the nuts 13, and the provision of these recesses permits the tank to be constructed of greater size than would be possible if its sides were fiat throughout their areas, since when employing such a construction, the upper portions andthe corners of the tank would necessarily be substantially in line with the inner edges of the bars 19, instead of being spaced outwardly from said bar edges as disclosed in Figs. 2 and 3.

In the foregoing I have described one embodiment of my invention, and such embodiment has been illustrated, but I wish it understood that the device may be constructed in other forms and that numerous changes may be made within the scope of the invention as claimed.

I claim;

1. In a hog oiler, a tank open at its upper end, oil pans on the exterior of said tank and communicating therewith, oil applying members rotatably mounted on the exterior of said tank and dipping into said oil pans, vertical bars secured on the inner side of the tank to reinforce them against. the rubbing of the hogs upon said oil applying members, said bars having inwardly extending shoulders near their lower ends, and an oil reservoir for supplying oil to said tank, said reservoir being removably received in said tank and being supported by said shoulders. 1

2. A structure as specified in claim 2, said reservoir having recesses in its sides receiving said bars.

3. In a 110g oiler, an oil tank, an oil pan on the exterior of said tank supplied with oil from the latter, the wall of said tank having a vertical slot, a bearing member contacting with the outer side of said wall, an oil applying member rotatably mounted on said bearing member and dipping into said oil pan, a bolt passing inwardly through said oil applying member and through said bearing member and slot, a shoulder on said bolt contacting against the outer side of said bearing member, and a nut on the inner end of said bolt contacting with the inner side of the tank wall for clamping said bearing member and bolt in vertically adjusted position.

4:. In a hog oiler, an oil tank open at its upper end, oil applying means on the exterior of said tank and supplied with oil from the latter, an oil reservoir removably received in said oil tank, a valve seat in the bottom of said reservoir, a downwardly opening valve engaging said seat for controlling the discharge of oil into said tank, a stem rising from said valve, a stem guide through which said stem passes, said guide contacting with but being unsecured to the reservoir bottom, a spring thrusting downwardly on said guide and upwardly on said stem to' exert a closing power on said valve and to retain said stem guide in contact with the reservoir bottom, and a filling plug threaded in the top of the tank and capable of being forced downwardly on said stem to open said valve, said stem and stem guide being removable through the filling opening when the valve is removed from the stem.

, In testimony whereof I have hereimto set my hand.
